mimiFoto is a little application designed for people who want to easily change their iPhoto, Preview or Mail icon.
If you have such icons sitting in your Dock, you may want to have your own private image instead of the default sunset, the little kid or the stamp. With mimiFoto, this becomes as easy as drag-n-drop!
Note that no permanent changes are made to the patched applications. mimiFoto works the same way you change an icon with the info window of the Finder: it's a simple copy-paste.
Please also note that this application is beta software. It has initially been created because of a private need, and I thought it would be nice to share it with other Mac users.
